Experimental results - slope and intercept
(N.B. Due to the finite time required for the potential step to be complete, the
data in the first few milliseconds of potential step experiments is often distorted.
The BAS 100W
Auto
option therefore only uses the last 80% of the collected
data when calculating slopes and intercepts).

In addition to the
Results Graph
, the
Results Graph
window also displays the
coordinates of the mouse cursor as it is moved within the axes. A selected area can be
expanded (Zoomed) by dragging the mouse (using the left mouse button) between
diagonally opposite corners of the defining rectangle. This operation can be reversed
by clicking the left mouse button.
When using the
Manual
option, the baselines for calculation of results are defined by
the user. Click and hold down the
right
mouse button at the starting point of the
baseline and drag the mouse across the graph to the end point of the baseline. As the
mouse is moved within the
Results Graph
window, the coordinates of the mouse
cursor are shown in the lower left corner. The number of baselines that must be
defined depends on the nature of the plot:
a) Symmetric and tail curves - define one baseline
b) Sigmoidal curves - define two baselines
c) Straight line plots - define two points on the X axis
For symmetric and tailed plots, the peak area is also listed in the Main window (the
peak area is the area between the curve and the user-defined baseline (Figure 7-1)).
